Plunger Adjustment
8. Plunger Adjustment
When properly adjusted, the plunger should
tightly grip a 1.25" (31.8 mm) round bar
(Figure 14) when activated and retract far
enough when de-activated to allow easy removal
of a 1.63" (41.4 mm) diameter drawbar.
1. To adjust plunger, loosen the jam nut
from plunger adjustment nut and
rotate adjustment nut to increase or
decrease the plunger engagement
(Figure 15).
IMPORTANT: Holland plungers have
an adjustment range
of approximately 1.50"
(38.1 mm). The plunger
is pre-set at the factory
to provide approximately
1.00" (25.4 mm) of
adjustment out or 0.50"
(12.7 mm) adjustment
in. At no time should
the push rod have less
than 0.38" (9.5 mm)
engagement with the
plunger (Figure 15).
2. After adjusting the plunger, retighten
the jam nut securely against plunger
adjustment nut .
